is there a quicker way to set up form calculations

I have a table where I want "price" mulitpled by "selected #" of product to get a "total". I know you can do a simple calculation to get the answer, but there are 200 items in the table and it takes way too long for me to select each field using the simple mulitplation function under the calcalulation tab. If this were excel, when you duplicated the total column it would automatically change the formula so that it would look up the information in the next row. When you duplicate the total field in acrobat it has the same exact formula in all the duplicates.
